Cleanup Keystore API
Rename confusingly named methods, add userID arguments to all methods
that operate on user state and delete methods that have been replaced by
the onUser* methods.
Some of the old methods have been kept in KeyStore.java in order to ease
the transition of various system packages to the new methods.
(cherry-picked from commit d8aacca3a197f65021e9b520807b7315b7a59d68)
